Luke Bobnar Watershed Scientist
This summer we spent roughly three weeks constructing a valley-wide stream and riparian habitat improvement project in Little Arnot Run in the Allegheny National Forest. WPC and partners have been monitoring this stream for a few years and collecting pre-construction data on multiple parameters. One specific study area looks at the wild trout breeding behavior response to our work by surveying trout nests, called "redds" (found in the gravel/substrate of the stream). We hypothesized that we’d see an increase in breeding activity at the site, and incredibly did only 1.5 months after the heavy equipment shut off. That seemed REALLY
quick for fish return, but, lo and behold, while surveying this past October, there were a pair of wild brook trout making a redd right on top of one of our structures!
Granted, the scope of research on this project touches almost every field of study related to terrestrial-riparian-stream valley ecosystems and the host of plants and animals that utilize them; but speaking from the "trouty" end of things, seeing native wild trout breeding where you worked, that’s pretty cool! We also observed trout spawning in undisturbed sections of the watershed, where we will be working by hand this spring without heavy equipment.
